Voltage-dependent varistors (VDRs) are uniquely designed devices that provide overvoltage and overcurrent protection for electric circuits and delicate electrical components. To meet the needs of designers, manufacturers are developing cutting-edge devices like B72660M0170K072 that are designed for use in Circuits up to 790VAC. In particular, B72660M0170K072 application field and working principle is a key topic in the design of reliable power control systems.

The B72660M0170K072 is an AC mounted metal-oxide-varistor (MOV) designed as an overvoltage/overcurrent suppression device. It is composed of a solid ceramic body filled with zinc-oxide grains that are embedded in a matrix of epoxy resin. The zinc oxide grains act as the varistor element, absorbing excess voltage and current until the component reaches its maximum “breakdown” voltage. The MOV is then able to short-circuit the current, preventing further voltage spikes.

In addition, the B72660M0170K072 is equipped with an inbuilt thermal protection device. This is designed to automatically shut down the device when the temperature reaches 140°C, protecting the circuits and preventing a hot spot from developing. This thermal protection function is also helpful in preventing electrical surges from entering the system.

The B72660M0170K072 is designed to be installed into applications such as general equipment control and industrial systems. The device is able to withstand peak ratings of 790 VAC, making it perfect for protecting power controllers, high voltage electricity grids, and various types of industrial machinery. In addition, the device is equipped with fast response times, allowing it to absorb and discharge a high amount of transient voltages.

When it comes to the working principle of the B72660M0170K072, the device operates in a similar fashion to a Zener diode. The zinc-oxide grains act as tiny capacitators, enabling them to store and release electricity over a wide range of frequencies. In essence, the device functions as an energy absorber, which is why it is widely used for overvoltage and overcurrent protection.

As an integral component of any application where power control is essential, the B72660M0170K072 is a reliable and efficient device. It is designed to absorb a wide range of transient voltages, and its fast response time makes it the perfect choice for protecting delicate electrical components from damage. Additionally, its built-in thermal protection ensures that the device does not become a source of excessive heat, allowing it to provide years of reliable service.
